Fix SVG scaling in QML

For some reason, the default QML Image element doesn't scale SVGs like
it should. Essentially, it just reads the source size of the SVG and
scales it like it would a regular image (say PNG).

I'm fixing this by manually setting the source size of the image to the
current size. That said, this is in my opinion a hacky fix and it's
really weird that QML doesn't special-case SVGs and scale them as it
should.
